Analysis

Total drink: ~180g (2 oz rum, ¾ oz lime, ½ oz simple, soda top, muddled mint)

Component Amount % of drink
Alcohol (ethanol) ~19g 10.5%
Sugar ~8g 4.2%
Water + dilution ~153g 85.3%

A long, refreshing sour — ~11% ABV finished, lightly sweet. The soda top roughly doubles the glass, dropping the rum to session strength; mint is aromatic, not structural. The simple syrup and lime hold the balance — the whole drink lives or dies on cold soda and gentle muddling (bruise the mint for oils, don’t shred it).

Notes

  • Slap the mint sprig firmly on the back of your hand before garnishing — this releases the aromatic oils.
  • Don’t over-muddle the mint leaves. You want the oils, not shredded leaves in the drink.
